Application filed September 10, 1890. Serial No. 364,575- (No model.)

To all whom it may concern:

Be it known that I, CHARLES MILLER, of Washington, in the county ofFranklin and State of Missouri, have invented a new and Improved Toolfor Cutting Pipe or Anything Round; and I do hereby declare that thefollowing is a full and exact description of the said invention.

The nature of my invention consists in oonstructing a tool thatWillleave the pipe in its original shape without staving it in oroutside, thus preventing narrowing the inside passage of the saine, norswelling the outside to prevent the screw-die to Vtake a start. Besides,it is a self-regulating cutter, self-oiling when in use, and cheap,durable, convenient, and simple.

A and B represent the tool in operation, except the outlet for oil,Which is closed.

A represents the lower half, which is a holloW cup forming anoil-chamber; has a cap at a, but is solid and flat at b, with an openslot in it to receive the regulating-screw With its thumb-nut. At Cthere is a thumb-screw,

which serves as a valve for the oil-chamber and regulates the outflowWhen used. B represents the upper half, with clamp d at one end,fastening to the main bar B with a hingejoint, and slipping with itsround part on tube A, and regulates the position of the cuttingknife byslipping it forward and backward. B is a split at the other end toreceive both the cutter as Well as the regulating-screw.

e and f are cutter and guide, Fig. l. e is the cutter, and f is a guideto prevent the cutter e to enter into the metal too deep, thus avoid ingbreakage. e and f can be made separate or in one piece.

g is a screw or bolt to hold cutter and guide 1n.

h is a swivel-jointat the end of bar B, connecting regulating or feedscrew with its thumb-nut i.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

l. A self-oiling tube forming a part of a pipe-cutting tool, asdescribed.

2. A cutting device to prevent the cuttingedge to enter the metal anydeeper than desired, to prevent breaking, as described.

3. The combination of the Whole as a tool for cutting pipe or anythinground, in the manner described, and for the purpose set forth.
